Beamer breaks enumitem when using [<+->]

Question

In the MWE below, if I comment out the use of enumitem everything works fine, but with it included it breaks. Is there a way to have this working?

\documentclass{beamer}

\usepackage{enumitem}

\begin{document}

\begin{frame}{title}

\begin{enumerate}[<+->]
    \item How
    \item are
    \item you?
\end{enumerate}

\end{frame}

\end{document}

If I use the following code I get the error: Package enumitem Error: <+-> undefined.

\documentclass{article}\usepackage{beamerarticle}

\mode<article>{\usepackage{enumitem}}

\begin{document}

\begin{frame}{title}

\begin{enumerate}[<+->]
    \item How
    \item are
    \item you?
\end{enumerate}

\end{frame}

\end{document}

You shouldn't load enumitem in beamer. Beamer already has its enumeration facilities, which are incompatible with enumitem's. — Phelype Oleinik, Sep 07 '18 at 15:32
@samcarter I have one source file which can be used to create a beamer presentation, handouts and an article mode. I'm using the enumitem in the article mode. — Geoff, Sep 07 '18 at 15:41
@Geoff And for what do you need it in article mode? (Am just trying to find out if there isn't another way without the enumitem package) — samcarter_is_at_topanswers.xyz, Sep 07 '18 at 15:46
@samcarter I can't answer that exactly, I'm probably using it for many purposes. One that comes to mind though is to resume. — Geoff, Sep 07 '18 at 15:49
@Geoff You could resume list like this: https://tex.stackexchange.com/a/298810/36296 — samcarter_is_at_topanswers.xyz, Sep 07 '18 at 15:52
@Geoff Would the same enumerate environment be present in your article and in your beamer version? — samcarter_is_at_topanswers.xyz, Sep 07 '18 at 15:54
@samcarter It'll be easier for me to just delete the \begin{enumerate}[<+->] than it would to start changing all the uses of enumitem. That's why I posed the question the way I did. — Geoff, Sep 07 '18 at 15:56
@samcarter Actually all occurrences of \begin{enumerate}[<+->] are wrapped in frames a such \begin{frame}<presentation> so they play no role in the article mode (except to return errors). — Geoff, Sep 07 '18 at 15:59

If you want to load the enumitem package to use it in article mode, you can restrict the loading to this mode.

Then one just has to hide [<+->] from the enumitem package, which can be done with \beamerdefaultoverlayspecification{<+->} either globally or locally.

%\documentclass{beamer}

\documentclass{article}
\usepackage{beamerarticle}

\mode<article>{
\usepackage{enumitem}
}

\begin{document}

\begin{frame}{title}

{
\beamerdefaultoverlayspecification{<+->}% <- can also be used in the preamble if it should apply to all itemization/enumerate
\begin{enumerate}
    \item How
    \item are
    \item you?
\end{enumerate}
}

\end{frame}

\end{document}
